Phosphonic acid, (1,2-dicyanoethyl)-, diethyl ester, also known as diethyl (1,2-dicyanoethyl)phosphonate, is an organophosphorus compound with the chemical formula C9H14N2O2P. It is a colorless liquid with a molecular weight of 220.19 g/mol. Phosphonic acid, (1,2-dicyanoethyl)-, diethyl ester is characterized by the presence of a phosphonic acid group, two cyano groups, and two ethyl ester groups. It is synthesized through the reaction of diethyl phosphite with 1,2-dibromoethane, followed by the addition of sodium cyanide. Diethyl (1,2-dicyanoethyl)phosphonate is used as a reagent in organic synthesis, particularly in the preparation of various phosphorus-containing compounds and as a ligand in coordination chemistry. Due to its potential toxicity and reactivity, it is important to handle Phosphonic acid, (1,2-dicyanoethyl)-, diethyl ester with care and in accordance with proper safety protocols.

7749-93-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7749-93-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,4 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7749-93:
(6*7)+(5*7)+(4*4)+(3*9)+(2*9)+(1*3)=141
141 % 10 = 1
So 7749-93-1 is a valid CAS Registry Number.
